It sounds to me like they are making something...and it may very well be of historic proportions.
What a mixture of gangsters/islamic-fascists, and supposably freedom loving peace-niks. Calling people "brothers and sisters" from the podium and then demanding that H.Rap Brown, the convicted cop-killer be freed. (I didn't watch the whole thing. Did someone stand up and put in a good word for NAMBLA?)
I don't see how any one individual could have sat through the whole thing and not realized that there were totally odious people on stage, leading the chants. What a motley crew. What luddy-duddies. Moon-calves and Jabberknowls.
(I don't know exactly what those last three adjectives mean. I saw a W.C. Fields movie recently and they're sort of music to my ears right now. Anyway, I bet that's what they are. And they shouldn't like being like that).
